Analog mechanical readout, single-stage heat\/cool, high and low fan speeds, and an Auto\/On fan mode switch. Black case, no programming, no screen to fuss with.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Coleman 9420-351 is a straightforward 12-volt DC wall thermostat for your RV's heating and cooling system. It's the analog version, so you get a simple mechanical readout instead of a digital screen. Slide the lever, set your temperature, and you're done. No menus, no programming, nothing to fuss with when you're setting up camp.\u003c\/p\u003e\n\u003cp\u003eThis is a single-stage control, which means it handles one stage of heating and one stage of cooling. You pick the mode you want and the thermostat holds the cabin at your setting. It's built for the way most owners actually use their rigs. Warm it up on a cold morning, cool it down in the afternoon, and leave it alone the rest of the day.\u003c\/p\u003e\n\u003cp\u003eFan control is where this unit earns its keep. You get high and low fan speed settings, so you can move a lot of air fast or keep things quiet overnight. There's also an Auto\/On fan mode switch. Set it to Auto and the blower only runs when the system is actively heating or cooling. Flip it to On and the fan runs continuously, which is handy when you want steady air circulation through the coach.\u003c\/p\u003e\n\u003cp\u003eThe black case keeps it low-key against darker interior walls, and the layout is clean and easy to read at a glance. If your old Coleman-Mach analog thermostat has quit or the lever feels sloppy, this is the direct mechanical replacement that keeps everything working the way you're used to.\u003c\/p\u003e\n\u003cp\u003eA few things to know before you wire it in. This is a 12-volt DC control, so it's meant for RV systems, not household line-voltage setups. And because it's single-stage with a manual mode selection, it won't automatically switch itself between heat and cool. You choose the mode. For a lot of folks, that simplicity is exactly the point. Fewer things to break, and you always know what it's doing.\u003c\/p\u003e\n\u003cp\u003eWiring is basic low-voltage work. If you're comfortable with a screwdriver and can match up the existing wires, you can swap this in an afternoon. If you're not sure, any RV service tech will have it done in minutes.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e12 Volt DC operation, wired for RV heating and cooling systems\u003c\/li\u003e\n  \u003cli\u003eSingle-stage heat\/cool control for straightforward one-stage temperature management\u003c\/li\u003e\n  \u003cli\u003eMechanical readout, no screen or programming to deal with\u003c\/li\u003e\n  \u003cli\u003eHigh\/Low fan speed control to move air fast or keep it quiet overnight\u003c\/li\u003e\n  \u003cli\u003eAuto\/On fan mode switch, run the blower only when needed or continuously\u003c\/li\u003e\n  \u003cli\u003eBlack case blends into darker interior walls\u003c\/li\u003e\n  \u003cli\u003eDirect mechanical replacement for analog Coleman-Mach wall thermostats\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Coleman reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eIs the Coleman 9420-351 analog or digital?\u003c\/summary\u003e\n    \u003cp\u003eIt's analog.
